- Gabbro - Wikipedia
Gabbro is a coarse-grained (phaneritic) igneous rock that is relatively low in silica and rich in iron, magnesium, and calcium Such rock is described as mafic Gabbro is composed of pyroxene (mostly clinopyroxene) and calcium-rich plagioclase, with minor amounts of hornblende, olivine, orthopyroxene and accessory minerals [4]
- Gabbro | Properties, Formation, Composition, Uses
Gabbro is a type of intrusive igneous rock that is coarse-grained and dark-colored, typically composed of calcium-rich plagioclase feldspar, pyroxene, and sometimes olivine It is similar in composition to basalt, which is its extrusive equivalent

What is Gabbro? Gabbro is a coarse-grained, dark-colored, intrusive igneous rock It is usually black or dark green in color and composed mainly of the minerals plagioclase and augite It is the most abundant rock in the deep oceanic crust Gabbro has a variety of uses in the construction industry
- Gabbro: Composition, Types, Properties, Uses - Geology In
Gabbro is the intrusive equivalent of basalt, which is its extrusive counterpart formed from the same type of magma but cooled rapidly at the surface Much of the Earth's oceanic crust is made of gabbro, formed at mid-ocean ridges
- Gabbro | Igneous Rock, Mafic Minerals Plutonic Intrusions - Britannica
Gabbro, any of several medium- or coarse-grained rocks that consist primarily of plagioclase feldspar and pyroxene Essentially, gabbro is the intrusive (plutonic) equivalent of basalt, but whereas basalt is often remarkably homogeneous in mineralogy and composition, gabbros are exceedingly
- Gabbro: The Intriguing Coarse-Grained Igneous Rock . . . - Rock Seeker
Gabbro is a dense, coarse-grained igneous rock that forms deep beneath the Earth’s surface as slow-cooling magma solidifies It shares the same composition as basalt but cools slowly enough for its minerals to grow large and become visible to the naked eye
- Gabbro: A Coarse-grained, Dark-Colored Plutonic Rock
Gabbro is a dense, coarse-grained, dark-colored, mostly plutonic rock Its essential minerals are calcic plagioclase and pyroxene, but it may have minor amounts of amphibole, olivine, and other minerals
- Gabbro Rock (Facts, Composition, and Uses) Lots of Pictures
Gabbros are igneous rocks that are characterized by their mineral composition of pyroxene and plagioclase feldspar When looking at the rock’s surface you’ll notice the very coarse-grained texture, with the crystals within the rocks being large and easily visible Gabbro is also considered mafic
